2008-10-28sh: Fix FPU tuning on toolchains with mismatched multilib targets.Paul Mundt
Presently there is very little standing in the way of using an SH-4 toolchain for building an SH-2 kernel, and vice versa. Binutils itself has no limitations whatsoever and supports explicit ISA hinting, which we already use with varying degrees of success today. This leaves GCC as the odd one out, due to a rather dubious policy decision by the GCC folks to not include all of the CPU family variants in the default list of multilib targets in GCC4. Despite best efforts to the contrary, libgcc itself already contains awareness of the various CPU types and remains generally usable, allowing it to safely be referenced even on a mismatched target (and indeed, explicit ISA tuning by binutils keeps us honest in terms of ensuring that we do not link incompatible objects in). In order to support this, a couple of changes had to be made. Firstly, the introduction of MAYBE_DECLARE_EXPORT(), which provides a __weak extern reference for libgcc resident routines when finer-grained -m<cpu-family> based tuning is not supported by the toolchain. This fixes up the __sdivsi3_i4i and __udivsi3_i4i references when dealing with SH-2 kernels linked with an SH-4 libgcc. Secondly, in case where we are unable to find a suitable match for CPU family tuning but still have a toolchain that defaults to FP instruction generation, a suitable nofpu target must be selected. This is accomplished by selecting the first nofpu multilib target supported by the toolchain, which is also necessary for selecting the proper libgcc to link against.

2008-10-22sh: improve pinmux support for single direction pinsMagnus Damm
This patch improves the support for gpio pins that are hard wired to either input or output and lack control register association.

2008-10-21sh: Update gpio_set_value() pin value handlingMagnus Damm

2008-10-21sh: Wire up oops reporting in the die notifier chain.Paul Mundt
Commit 3f5a54e371ca20b119b73704f6c01b71295c1714 ("ftrace: dump out ftrace buffers to console on panic") added an ftrace buffer dumper that hooks in to the die notifier chain and dumps out data in the oops path. Unfortunately SH supported ftrace but didn't support DIE_OOPS, so add that in and get it building again. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-10-20kdump: make elfcorehdr_addr independent of CONFIG_PROC_VMCOREVivek Goyal
o elfcorehdr_addr is used by not only the code under CONFIG_PROC_VMCORE but also by the code which is not inside CONFIG_PROC_VMCORE. For example, is_kdump_kernel() is used by powerpc code to determine if kernel is booting after a panic then use previous kernel's TCE table. So even if CONFIG_PROC_VMCORE is not set in second kernel, one should be able to correctly determine that we are booting after a panic and setup calgary iommu accordingly. o So remove the assumption that elfcorehdr_addr is under CONFIG_PROC_VMCORE. o Move definition of elfcorehdr_addr to arch dependent crash files. (Unfortunately crash dump does not have an arch independent file otherwise that would have been the best place). o kexec.c is not the right place as one can Have CRASH_DUMP enabled in second kernel without KEXEC being enabled. o I don't see sh setup code parsing the command line for elfcorehdr_addr. I am wondering how does vmcore interface work on sh. Anyway, I am atleast defining elfcoredhr_addr so that compilation is not broken on sh.

2008-10-20sh: Only build in gpio.o when CONFIG_GENERIC_GPIO is selected.Paul Mundt
The pinmux management is tied in to this code, while it is presently only used by platforms that select GENERIC_GPIO. The asm/gpio.h definitions are not referenced when GENERIC_GPIO is disabled, resulting in a build failure for all of the platforms that don't select it.

2008-10-04sh: More I/O routine overhauling.Paul Mundt
This tidies up a lot of the PIO/MMIO split. No in-tree platforms were making use of the MMIO overloading through the machvec (nor have any of them been in some time), so we just kill all of that off. The ISA I/O routine wrapping remains unaffected, which remains the only special casing outside of the iomap API that boards need to think about. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-09-21sh: Trivial trace_mark() instrumentation for core events.Paul Mundt
This implements a few trace points across events that are deemed interesting. This implements a number of trace points: - The page fault handler / TLB miss - IPC calls - Kernel thread creation The original LTTng patch had the slow-path instrumented, which fails to account for the vast majority of events. In general placing this in the fast-path is not a huge performance hit, as we don't take page faults for kernel addresses. The other bits of interest are some of the other trap handlers, as well as the syscall entry/exit (which is better off being handled through the tracehook API). Most of the other trap handlers are corner cases where alternate means of notification exist, so there is little value in placing extra trace points in these locations. Based on top of the points provided both by the LTTng instrumentation patch as well as the patch shipping in the ST-Linux tree, albeit in a stripped down form.
